How Text-Based Diagramming (Mermaid.js) Is Changing Process Design and Coding?

Most of us who manage systems, implementations, or process documentation know the struggle:

Diagrams are essential, but creating and maintaining them is painful

  • Shapes don’t align. Arrows overlap

  • Updates take forever

Now imagine a world where every diagram, workflow, process map, or architecture is just text:

  • Editable

  • Version-controlled

  • Dynamically generated

That’s Mermaid.js, the open-source standard that’s redefining how visual thinkers and system builders communicate.

What Is Mermaid.js?

Mermaid is a text-based diagramming language that turns simple lines of text into rendered visuals: flowcharts, sequence diagrams, Gantt charts, class diagrams, and more.

Instead of dragging boxes and arrows, you write this:

graph LR
  A[Sales Order Approved] --> B[Generate Invoice]
  B --> C[Send to Customer]
  C --> D[Receive Payment]

and Mermaid instantly produces a clean diagram like this one:

It’s now supported natively in tools like GitHub, Notion, Obsidian, Microsoft Loop, and even Claude, becoming a de facto standard for technical and business documentation.

What You Can Create with Mermaid 🧩

Mermaid isn’t limited to flowcharts — it supports a wide range of diagram types that cover both business and technical use cases:

  • Flowcharts for approvals, onboarding, or integrations

  • Sequence diagrams to show system interactions or API calls

  • Gantt charts for project timelines and implementation plans

  • Class and entity-relationship diagrams (ERD) for data modeling

  • And more

Each chart can be customized with styling and formatting controls, colors, line types, shapes, and labels, to fit your visual language. You can even embed icons, links, and images inside nodes and notes to make diagrams more intuitive or visually aligned with your brand.

Because it’s text-based, these visual decisions are consistent and reusable; you can define styles once and reuse them. Its structure and aesthetics working together by design.

Why It’s Gaining Momentum

Mermaid reflects a bigger trend: the move toward text-first collaboration and dynamic documentation.

Here’s why teams are adopting it fast:

  • Versionable & diffable: diagrams stored as text evolve with your repo, code, or SOPs

  • Low friction: requires no special tools; any text editor works, though there is a modest learning curve

  • Automation-friendly: diagrams can be generated from data or APIs

  • Lightweight: no heavy design software or binary files

  • Supported everywhere: it’s now embedded in major documentation and AI tools

Why We Use It at Origami Precision💡

At Origami Precision, we help growth-stage and VC-backed software companies scale delivery, streamline onboarding, and document systems clearly. Mermaid fits right into that mission.

We use it to:

  • Map client workflows and data flows during CRM, ERP, and SaaS implementations

  • Visualize approval processes, integrations, and customizations in Salesforce.com, NetSuite, and similar platforms

  • Keep process documentation in sync with configuration and code repositories

  • Brainstorm with structure - turning early whiteboard ideas into scalable visual assets

The Superpower: Dynamic, Data-Driven Diagrams

Because Mermaid diagrams are text, you can generate them programmatically. This is where it gets exciting.

You can:

  • Build scripts that read your system model and auto-generate process diagrams

  • Pull real-time data (like order counts or workflow status) into your diagram nodes

  • Create interactive dashboards where visuals update as data changes

This turns a static “flowchart” into a living visualization of your operations. It’s documentation or dashboarding that evolves with your business,  not one that lags behind it.

AI + Mermaid = Next-Level Productivity✨

Tools like ChatGPT and Claude now understand Mermaid syntax; they can consume and produce Mermaid markdown. That means you can:

  • Convert old diagrams and screenshots into editable text versions
    Instead of redrawing legacy process maps, you can extract their structure using AI image understanding. This turns static visuals into live, versionable diagrams that can evolve with your systems.

  • Auto-generate diagrams from descriptions, CSVs, or workflow logic
    Describe a process in plain English, or feed AI a structured data file — it can instantly create clear Mermaid diagrams that reflect your operational flow. This accelerates early design and helps non-technical teams visualize systems faster.

  • Modernize legacy documentation quickly and collaboratively
    Teams can use AI to refactor scattered Visio charts, PowerPoints, or PDFs into consistent, text-based documentation. The result: cleaner handoffs, easier updates, and documentation that finally stays in sync with your codebase.

  • Generate code from sample Mermaid workflows
    Because Mermaid diagrams capture business logic unambiguously, AI can translate those flows into code that aligns closely with how your organization actually works. Clearer diagrams mean cleaner, more business-aligned implementations, bridging the gap between process design and execution.

Where to Start?

If you’re new to Mermaid.js, begin with simple flowcharts for your customer (and employee) onboarding or billing process. Tools like ChatGPT or Claude can instantly generate the syntax. As your library grows, you’ll have a text-based archive of every business process, editable and scalable over time.

✔️Takeaway

Mermaid.js isn’t just a tech curiosity - it’s a shift in how teams think, document, and communicate.

  • 👀 For visual thinkers, it bridges structure and creativity

  • 👥 For implementation teams, it reduces friction and brings clarity

If you’re in process management, documentation, or system implementation, start small - sketch your next workflow in Mermaid. You might find it’s not just faster… It's transformative!
